The 168th time apparently wasn't a charm for Brooklyn sex offender Gian Verdelli, who was arrested for the 169th time Monday for some (alleged) unwelcome "grinding" of two women several times over the past two months.

According to authorities, a 28-year-old Jersey City woman has had three perv-y run ins with Verdelli since June while riding on the PATH train.

Another woman also went to authorities about Verdelli's alleged pervy-ness on the PATH, which prompted police to set up an undercover sting in an attempt to catch the veteran pervert.

One of the victims managed to snap a photo of Verdelli on her cellphone following a July 3, attack. Police used the photo to identify Verdelli in the sting.
